Molecular biology is the study of the genetic makeup of organisms at the level of deoxyribonucleic acid (DNA). It encompasses the study of the ways in which diseases and traits can be passed through the genes especially via from parents to their offspring’s. Genes are the hereditary unit or genetic material that is transmitted from […]

Bacteria (singular: Bacterium) is one of the two important members of the prokaryotes (i.e. cells in which the chromosomes are not separated from the cytoplasmic membrane). The second is Archaea. Bacteria are prokaryotic organisms with very simple cell structure. They are single-celled organisms with complex cell wall. Bacterial cells are the simplest possible forms of

Microorganisms including bacteria, fungi, actinomycetes and viruses possess some unique qualities different from animals and plants. And these special characteristics of microbe’s warrants there continued usage for most of the industrial and/or biotechnological processes that produce goods and services that are of huge economic importance. Microorganisms require cheap nutrients for growth and they grow and

Inoculating loop or wire loop is a general purpose piece of instrument that allows microbiologist to transfer microorganisms in an aseptic manner from one place to another. Colonies of microbes growing on culture media plates of slants can be transferred onto glass slides or fresh culture medium for further studies, and this is only made
A Acetogenesis is mainlycharacterized by the formation of acetate. It is the process of forming acetate by acetogens through a variety of metabolic pathways including homoacetate fermentation, mixed acid fermentation and propionic acid fermentation. Acetogens are bacteria that produce acetate as their sole end product from certain sugar fermentation. Acetobacterium species, Clostridium aceticum and C.

Germ theory of disease is the theory that human infectious diseases are caused by specific variety of microorganisms including but not limited to bacteria, fungi, protozoa and viruses. This very important theory of microbiology was postulated by Louis Pasteur, a French microbiologist in 1857 when he tried to unmask the reason why beer and wine

Spontaneous generation (abiogenesis) is the mistaken hypothesis that living organisms are capable of being generated from non-living things. Mankind for many centuries (even till the time of Aristotle in 4th century BC) previously believed that non-living things such as meat and even decaying organic matter can generate living things (e.g. maggot). The belief that life

Born on the 6th of April, 1928, James Watson is an American molecular biologist, geneticist, and zoologist, who is best known as a co-discoverer of the structure of deoxyribonucleic acid (DNA) in 1953. Watson co-discovered the structure of the DNA with Francis Crick (an English molecular biologist, biophysicist, and neuroscientist) in 1953. Watson and Crick
Francis Crick was an English molecular biologist, biophysicist, and neuroscientist. He co-discovered the molecular structure of the genetic material (DNA) with James Watson in 1953. Francis Crick showed in his work that genetic information flows from the DNA to RNA and then to protein; and he referred to this very important concept of molecular biology
